Objectives To evaluate the effect of increased vitamin D intake on vitamin D status, bone mass and bone turnover in young girls aged 12-13.
More specifically the effects on the following parameters will be assessed:
This work package will consist of a randomised double blind one-year vitamin D supplementation study. Primary effect parameter is change in bone mineral content and therefore study duration will be one year. A total of 225 subjects, 75 in each of the three groups: one control and two intervention groups, will be included Two dosages of supplementation will be used: 5 µg per day and 10 µg per day.
772 studies on the registry are indexed under Vitamin D Deficiency; 61 are open to participants now.
This study's enrollment of 225 is above the median of 77 across 564 interventional studies indexed under Vitamin D Deficiency.
